I am trying to open an activity (CryptoVars) when the user select a menu Item from the Main Activity but I get the Error of the title.
Here is my code:
java class:

<resources> <!-- Example customization of dimensions originally defined in res/values/dimens.xml (such as screen margins) for screens with more than 820dp of available width. This would include 7" and 10" devices in landscape (~960dp and ~1280dp respectively). --> <dimen name="activity_horizontal_margin">64dp</dimen> Any advice would be helpful and deeply appreciated.
